If I am going to spend over 200k for a headphone system the HE1 and the older HE90set is the only two i will even consider.I see it the same way, for me their DACs are the weak point though.
However, I have a feeling that STAX will come up with a better amp to pair with the new SRX9k as there are still market for those who will only use STAX amps for STAX products.
Their current T8000 amp is only a 8000serires as is nothing more than a improved 727, maybe in 1 or 2 years time they will come up with a true sucessor of the T2 aka T9000 and the SRX9k T9000 combo will perfectly replace the SR-Omega T2 as in the 90s.
I also suspected there is a economical reason why they dont launch the new T9000 at the same time, might be because of T8000 sales is not up to expectation and they are trying to let people who jump in the electrostatic game because of the SRX9k to buy T8000 then introduce the T9k later.
Given the nature that Edifier being a chinese company; STAX growing popularity within China and East Asia headfi market, and the trend that Chinese consumer like money no object stuff as they can afford it, I can see driving force for STAX to develop this new amp.
